TUBE-SUPPORT FOR OIL-WELLS.`

SPECIFICATION forming part of Letters Patent No. 760,682, dated May 24, 1904. y

Application filed October 24, 1903. Serial N0 178,395. (No model.) l

To @ZZ wiz/0711, t may concern:

Be it known that I, CHARLES CARD, a citizen of the United States, residing at Sackett, in the county of Elk and State of Pennsylvania, have invented a new and useful Tubing- Support for Oil- Wells, of which the following is a Specication. y

My invention is an improvement in supports for oil-tubing.

The object of my invention is to devise vmeans whereby the tubing may be supported at a point far enough below the surface to be out of danger of injury by heat. when an oil-derrick is struck by lightning or the well takes fire from any cause the heat so affects the collar of th'ewtubing that by reason of expansion the threads release theirl hold and the tubing drops into the well, causing a serious loss and resulting in great inconvenience to the operators. My invention overcomes this difliculty by providing a support having no supporting-threads at or adjacent its upper end and extending the lower threaded end a suicient distance below the surface of the ground so that heat from a burning well at the Surface will not affect the threads.

My invention consists of the novel features of construction and combination of parts hereinaiter described, particularly pointed out in the claim, and shown in the accompanying drawings, in which- Figure l is a vertical elevation showing my device in position, the intermediate portion of my support being broken out. Fig. 2 is a perspective view of the device detached, an intermediate portion being broken away.

f Fig. 3 is a perspective view of the supportingring.

Fig. 4 is a-plan view of the device, the

Wrench ybeing in position; and Fig. 5 is a perspective'view of the wrench.

In the drawings, A represents a portion of the derrick-frame or other suitable support, having an opening adapted to receive the tubing of my support. Resting on this frame or At present beamv A is an iron ring B, also perforated, as shown at B-, and havmg a vertical annular flange B? encircling the marginal portion B3 of the opening B.

The tubing-support C consists of an upper* cylindrical portion C', having on one, side a projecting longitudinal shoulder C2, and below the verticalV shoulder is a horizontal annular shoulder C3, adapted to seat ,itself valve' like in the seat formed in the ring B by the ange and marginal portion B3.

The lower main portion C3 of the tubingsupport is a straight hollow tube adaptedto lit in the opening in the vbeam A. rllhe support C has a cylindrical bore extending its entire length, ,which bore is threaded at its upper end, as shown at C4, and the lower end of the tube is exteriorly threaded, as at C5.

. An interiorly-threaded coupling Dis of a sufficient diameter at its upper end to t over the lower end of the tube C3, and at its lower end the'coupling is ofa diameter suflicient to receive the upper'end of the oil-tubing E.

A wrench F has a curved portion F adapted t0 lit over the portion C of the tubing-support',` anda notch F2, adapted to tit over the shoulder C2. A pipe from a pump may be fitted into vthe upper threaded end C4 of the tubing-support bore. The lower end C5 of the portion C3 willbe six or more feet under ground and Will not be affected by heat on the surface. j

Havingl thusfullyl described my invention,

vwhat I claim'asnewf'and desire to secure by Letters Patent,` is-l, g

A device of the kind described comprising a tube having a vertical, longitudinal shoulder at its upper end, ahorizontal annular shoulder below the vertical shoulder, and threaded adjacent its lower end.
